I am trying to wrap my head around some brake upgrades right now. I have a bike with twin disk brakes up front. Each caliper is a 38mm diameter single piston and the caliper slides on pins. The master cylinder is 5/8", or 15.9mm.
The brakes feel extremely "wooden". As soon as the pads make contact, the lever has no modulation at all, and there is not much braking power. I have to use 4 fingers and don't think I could lock up the front wheel in the rain if I tried.
I am thinking of putting some sport bike calipers on there, which commonly have 4 opposed pistons ranging from 30-34mm diameter, and leaving the master cylinder stock.
My question is how do I calculate the new ratio? If I count all the areas of the pistons, the ratio is MUCH larger, and I know from experience it doesn't really work that way. Do I only consider the pistons on one half of each caliper?
Any ideas?
